Uh. Doing a "gtar tvf" will mean you're limiting yourself by the speed of 
the terminal, which in many cases aren't all that quick, while "gtar xvf" 
means you're limiting yourself by the disk.

Try something like "dd if=/dev/rst1 of=/dev/null bs=10240" and see if it 
That will make sure you're not limiting yourself by another device.

Apart from that, I'd expect there to be stops sometime when restoring from 
a tape. Creating and populating files don't happen instantaneous, and 
occasionally, the tape will have to wait a bit. Atleast that's what I 
would expect.
